DETROIT, March 8, 2016 /PRNewswire/ -- INFICON has released a new e-book to help auto manufacturers avoid pitfalls when selecting a leak detection method for the millions of tests they conduct each year on a wide variety of components and vehicle systems.
"Leak Testing in the Automotive Industry: A Comprehensive Guide to Leak Detection," can be downloaded, free of charge, at http://www.inficon.com/automotiveindustry-ebook.
The first part of the guide explains the basics of leak testing and outlines the strengths and weaknesses of the different methods for leak testing and leak location: from water bath and pressure decay, as well as vacuum decay, to testing with helium in accumulation and vacuum chambers. The e-book also covers the most common tracer gases – helium, hydrogen / forming gas and operating fluids like the refrigerants HFO-1234yf and CO2.
The second part of the e-book presents specific applications of different leak testing methods used in the automotive industry, according to Thomas Parker, INFICON's North American automotive sales manager. The e-book explains which components of a vehicle are typically tested, the test method that is used and outlines the leak rates that guide each test method.
This can range from air conditioning components, to drive train modules, to safety-related systems. The e-book also points out which applications that currently use older leak testing methods, like water bath or pressure decay, are reaching their limits of reliability and sometimes support the wrong conclusion.
The e-book also includes a detailed section on the Top 10 common errors in leak testing in the automotive industry. Common testing errors can include items such as contamination of the test piece, ignoring temperature or pressure influences during testing, or failing to identify stringer or gross leaks in the components.
INFICON is one of the world's leading developers, producers and suppliers of instruments and devices for leak detection in air conditioning, refrigeration and automotive manufacturing. The company has manufacturing facilities in Europe, China and the United States, as well as sales and service offices throughout the world.
